C# 工程注册 BHO 类型的 dll 注册成功,但是注册表没有相应键值,请帮忙

[global_biz]

Hi,

http://blog.csdn.net/yanghongchang_/article/details/9998827

我根据上面这个连接创建了一个 C# 工程,在注册 dll 的时候,我修改了下注册方法加入了弹出框,.

然后,在一台 windows 2008 r2 的机器上试验了一下注册这个 dll, 提示注册成功,也会弹出测试框 (System.Windows.Forms.MessageBox.Show("BHO TESTING.2..");). 但是,打开注册表并没有发现那个注册键存在, 请问是什么回事??

我查注册表的时候,发现是到了: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer 这个位置的时候, 在 Explorer 的下面不会有 Browser Helper Objects 这个子目录键存在.

代码是照抄那个连接里面的内容, 只是加多个提示信息在相应方法上.

        public static string BHOKEYNAME = "Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Browser Helper Objects";

        [ComRegisterFunction]
        public static void RegisterBHO(Type type)
        {
            System.Windows.Forms.MessageBox.Show("BHO TESTING.2..");
            RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);

            if (registryKey == null)
                registryKey = Registry.LocalMachine.CreateSubKey(BHOKEYNAME);

            string guid = type.GUID.ToString("B");
            RegistryKey ourKey = registryKey.OpenSubKey(guid);

            if (ourKey == null)
                ourKey = registryKey.CreateSubKey(guid);

            ourKey.SetValue("Alright", 1);
            registryKey.Close();
            ourKey.Close();
        }

        [ComUnregisterFunction]
        public static void UnregisterBHO(Type type)
        {
            System.Windows.Forms.MessageBox.Show("BHO TESTING..3.");
            RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);
            string guid = type.GUID.ToString("B");

            if (registryKey != null)
                registryKey.DeleteSubKey(guid, false);
        }

Thanks.

可能程序没执行成功

把System.Windows.Forms.MessageBox.Show("BHO TESTING.2..");

放到ourKey.Close();后面看看

我重新改了下弹出框,加多了输出,然后,测试的时候,是输出下面结果: 弹出框 2,6,8,10,11,12,13 这几个弹出框都弹出来,然后, cmd 提示注册成功.

[ComRegisterFunction]
public static void RegisterBHO(Type type)
{
    System.Windows.Forms.MessageBox.Show("BHO TESTING.2..");
    RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);

    if (registryKey == null)
    {
        System.Windows.Forms.MessageBox.Show("BHO TESTING.4..");
        registryKey = Registry.LocalMachine.CreateSubKey(BHOKEYNAME);
    }

    System.Windows.Forms.MessageBox.Show("BHO TESTING.6.." + BHOKEYNAME);

    string guid = type.GUID.ToString("B");
    RegistryKey ourKey = registryKey.OpenSubKey(guid);

    System.Windows.Forms.MessageBox.Show("BHO TESTING.8.." + guid);

    if (ourKey == null)
    {
        System.Windows.Forms.MessageBox.Show("BHO TESTING.10.." + guid);
        ourKey = registryKey.CreateSubKey(guid);
        System.Windows.Forms.MessageBox.Show("BHO TESTING.11.." + ourKey);
    }

    ourKey.SetValue("Alright", 1);
    System.Windows.Forms.MessageBox.Show("BHO TESTING.12.." + ourKey);

    registryKey.Close();
    ourKey.Close();

    System.Windows.Forms.MessageBox.Show("BHO TESTING.13..");
}

[ComUnregisterFunction]
public static void UnregisterBHO(Type type)
{
    System.Windows.Forms.MessageBox.Show("BHO TESTING..3.");
    RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(BHOKEYNAME, true);
    string guid = type.GUID.ToString("B");

    System.Windows.Forms.MessageBox.Show("BHO TESTING.5.." + guid);

    if (registryKey != null)
    {
        registryKey.DeleteSubKey(guid, false);
        System.Windows.Forms.MessageBox.Show("BHO TESTING.7.." + guid);
    }
    System.Windows.Forms.MessageBox.Show("BHO TESTING.9.." + guid);
}

然后, 可能是因为注册表的键值也没有, 所以, 当我打开 IE 测试 BHO 的时候, 好像根本就没反应, 下面的代码没有在页面加载完成的时候被调用: 没有弹出: System.Windows.Forms.MessageBox.Show("BHO TESTING...");

public class BHO : IObjectWithSite
{
    WebBrowser browser;
    HTMLDocument document;

    public void OnDocumentComplete(object pDisp, ref object URL)
    {
        System.Windows.Forms.MessageBox.Show("BHO TESTING...");
    }

    public int SetSite(object site)
    {
        if (site != null)
        {
            browser = (WebBrowser)site;
            browser.DocumentComplete += new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
        }
        else
        {
            browser.DocumentComplete -= new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
            browser = null;
        }
        return 0;
    }

    public int GetSite(ref Guid guid, out IntPtr ppvSite)
    {
        IntPtr punk = Marshal.GetIUnknownForObject(browser);
        int hr = Marshal.QueryInterface(punk, ref guid, out ppvSite);
        Marshal.Release(punk);
        return hr;
    }
.....

我重新将上面的 dll 放到 windows server 2003 上面运行, 同样的结果却成功注册与成功在 IE 运行 BHO. 这个问题是与 OS 的版本有关, 谢谢.

因为你写的注册表值被重定位到下面这个位置去了 HKEY_LOCAL_MACHINE\Software\WOW6432Node。 你可以用程序中的类在GUID到注册表中搜一下就skn 是因为64位OS的问题。 http://blog.csdn.net/pbymw8iwm/article/details/6931120
